After finality started lagging on kusama around 025-11-25 15:55:40 validators started seeing ocassionally this log, when importing votes covering more than one assignment. ``` Possible bug: Vote import failed ``` That happens because the assumption that assignments from the same validator would have the same required routing doesn't hold after you enabled aggression, so you might end up receiving the first assignment then you modify the routing for it in `enable_aggression` then your receive the second assignment and the vote covering both assignments, so the rouing for the first and second assingment wouldn't match and we would fail to import the vote. From the logs I've seen, I don't think this is the reason the network didn't fully recover until the failsafe kicked it, because the votes had been already imported in approval-voting before this error.
